Pain in the left side of your abdomen can be felt anywhere between your lower chest and the top of your pelvic area. The pain can be sharp, dull, constant or intermittent. In some case together with the left sided abdominal pain you will suffer from pressure, bloating or cramps. The left side of your abdominal area contains your stomach, part of your pancreas, left kidney, and part of your colon. Most cases of left-sided abdominal pain are short-lived and nothing to worry about. Even sharp pains in your abdomen could be a result of trapped gas, heartburn, or indigestion. Sometimes, dull aching pains that don’t go away could be a sign of a more serious health condition. If the pain persists and worsens, go to the ER ASAP.
